The goal of this pilot study is to learn if a class and hands-on-practice of ergonomic body positions - or specific ways to move the body while working to prevent injury - is valuable to training obstetrics and gynecology doctors. The main questions the study team aims to answer are:

• Will these lessons successfully teach the participants how to move bodies at work in a way that will prevent injury?
• Will the participants feel that learning and practicing such lessons helps to avoid injury while at work?

Researchers will compare training obstetrics and gynecology doctors that attend a class on ergonomics and have guided hands-on-practice of ergonomic body positions with training obstetrics and gynecology doctors that attend the class only to see if the first group learns and remembers how to move their bodies safely while working. All participants will attend a class that teaches basic ergonomic lessons before they are divided into two groups. Group 1 will practice common surgery skills on a model while being videotaped by an artificial intelligence application. The application will make a report on unsafe positions a participant does while practicing surgical skills. The Group 1 participant will then go over the report with one of the study supervisors to talk about ways that the participant can move safely while practicing the skills. The participant will then practice the skills one more time while being videotaped. The study supervisors will then compare the two reports to see if the participant improved.

Group 2 will also practice common surgery skills on a model while being videotaped. Group 2 participants will not get to see the report that the application generates or speak with the study supervisors about ways to move safely while practicing the skills.

There will be a follow up after two months to see if participants remembered what was learned during the class and during the hands-on practice lesson. All participants will again be videotaped. The study supervisors will compare the videos and reports from the last class to the most recent ones to see if the participants learned and remember how to move safely while working.

Participants in both groups will take a quiz about the lessons learned in the class before and after the class to determine what had been learned from the lesson. A survey about how useful and helpful the class was and hands-on practice sessions were will also be completed.

Researchers will compare obstetrics and gynecology residents that attend a module/lecture on surgical ergonomics and undergo guided hands-on-practice of ergonomic body positions with obstetrics and gynecology residents that attend the class only to determine if the intervention group learns and retains surgical ergonomics knowledge and skills. Potential participants will be sent an initial information email describing the study 2 and 1 weeks prior to planned intervention. Children, pregnant women, fetuses, neonates, or prisoners are not included in this research study. Those that do not have the capacity to consent will not be enrolled.

Informed consent and enrollment of those eligible to participate in the study will be obtained by one of the co-investigators via written signature on the day of the first session of the planned intervention potential participants will be informed that all tests, procedures, and their resulting data are for research purposes. Participants will be informed that no reimbursement or remuneration will be given during this study and will be assured that no personal health information will be accessed from the medical record during this study. Participants will also be informed that all survey and questionnaire data will be stored securely in an encrypted database and anonymity protected and will be informed of the potential risks of the study such as the potential for continued strain and overuse injuries in the control group. This anticipated risk will be minimized by permitting the group to participate in the SEE module/lecture and receive ergonomic feedback on videos and reports at the end of the second session. This study does not incur greater than minimal risk for participants. Participants will be informed of the potential benefits including access to education that otherwise may not received. Participation is completely optional and will not be tracked. Participants will sign a copy of the consent and will receive a copy of this consent.

Following enrollment, all participants will complete an anonymous survey (consisting of demographic information + pre-session knowledge quiz + discomfort questionnaire). All surveys will be administered on participants' phones and accessed via quick-response (QR) code. All participants will then complete a short module/lecture on surgical ergonomics. Participants then be stratified into junior residents (1st and 2nd year) and senior residents (3rd and 4th year). Randomization into intervention or control group within strata will be completed using the REDCap randomization feature and documented on the last page of the intake survey. Given the nature of this project, it would not be feasible to blind study participants and researchers. Therefore, there is no blinding in this study.

The intervention will occur over two sessions approximately 2 months apart. In the first session, participants in both groups will perform laparoscopic surgical skills exercises on a simulation trainer while being assessed using the artificial intelligence (AI) ergonomic application (app) TuMeke. The TuMeke AI ergonomics app is an artificial intelligence risk assessment platform that records video during work tasks and assess behavioral ergonomic risk based upon the previously validated Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment tools (RULA). The application assesses tasks for risk of developing work-related musculoskeletal disorders of the hand, wrist, elbow using the Strain Index. The application records video only and allows for blurring of subject face and background for participant confidentiality. Using the score reports and video generated by the TuMeke AI app, residents in the intervention group will

• Review the amount of time spent in ergonomic and non-ergonomic positions at the neck, right and left shoulders, right and left elbow, and back
• Review the total the total amount of time spent in unsafe ergonomic positions
• Receive directed feedback on ways to improve ergonomics and guided practice in ergonomically safe positions from study investigators Participants in the intervention group will then be videotaped and score reports generated a second time. Those who are randomized to the control group will not receive feedback on their scores, view their videos, or receive guided practice until session #2. At the end of the session, all participants will complete a second anonymous survey (consisting of knowledge quiz + session feedback).

At the start of the second session, participants in both groups will complete a second anonymous survey (consisting of knowledge quiz + discomfort questionnaire + session feedback). Both groups will perform laparoscopic surgical skills exercises on a simulation trainer while being assessed using the TuMeke AI app. The control group will then be permitted to review the score reports and video generated by the app as outlined above and will receive directed feedback and guided practice in ergonomically safe positions from study investigators. At the conclusion of the session, all participants will have the option to keep all videos and score reports generated from their personal sessions.

The research data and materials collected will be obtained for the specific purpose of research. The types of data collected will include:

• Demographic data
• Responses from pre- and post-module knowledge quizzes
• Scores from pre- and post-study modified Cornell Musculoskeletal Discomfort Questionnaire for standing work and dominant hand forms
• The rapid upper limb assessment (RULA), rapid entire body assessment (REBA), and revised hand strain index (RHSI) ergonomic risk score reports obtained from video recordings and generated by the AI app
• Responses to pre- and post-interventions survey

Redcap software through Montefiore institutional license and Box.com - Montefiore Medical Center's secure cloud content management account, will be used for data collection and storage. The surveys will be distributed via institutional email accounts and will be accessible via quick-response (QR) code to allow for completion on participants' phones. A message preceding the surveys will clearly state that the survey is optional and anonymous. Participants will be anonymously linked across pre- and post- education surveys by their study identification number. The demographic data, quiz, and survey responses, pain scores obtained by the surveys will be stored on the RedCap platform.

The videos of study participants blur out the subject's face using an in-app feature. The videos and the ergonomics reports generated from the TuMeke ergonomic app will be stored in password protected files and stored on the institutionally secured and managed network drive Box.com. There will be no information in the report or the videos which could be used to identify the participants. No video generated data will be stored in the TuMeke App, on personal phone, or a personal computer. All data will be accessed and all work will be conducted on password protected computers in non-public areas. The PI and coinvestigators will have exclusive access to the study data. At the conclusion of the study, study participants will have 2 weeks to request access to reports and videos generated by the TuMeke app. After this time, videos and the AI app-generated ergonomic scores reports pdf files will be permanently deleted.

As this is a pilot study, a formal sample size calculation was not performed. However, a data analysis plan including a power analysis was performed. The primary outcome of pain score was used for power and sample size considerations. The study that used a population and survey most similar to this planned study was used. First, to estimate the model study's standard deviation based on the interquartile range, of the sample population was estimated with the following equation:

S ≈ (q3-q1)/ (1.35)

This produced a standard deviation of 3.70. Then, the following equation was used to estimate the minimum sample size of a single population to estimate a mean:

n = (z2 x sigma2)/d2

The model study found an average change of 2 points for pain scores, d=2. Therefor a 95% confidence interval, z=1.96. The calculated sample size is n=13.2.

Paired two-sided T-test, Fischer's exact test, and univariate logistic regression will be used in univariate analysis. Pending variable distribution and univariate analysis, multivariate regression analysis may be performed. A significant level of 0.05 will be used. Feedback will be qualitatively analyzed using Grounded Theory and reported thusly. Excel and Stata will be used for analysis.

As this is a non-interventional protocol of standard clinical care, the study team does not expect there to be serious adverse events related to study participation. The PI will monitor for any risks to participants of being involved in the study, which are deemed to be low given the absence of an intervention or change in clinical management. However, there may be unanticipated problems or issues that arise during this research study that warrant reporting, evaluation, and possible changes in procedures or documents. The Office for Human Research Protections (OHRP) considers unanticipated problems involving risks to subjects or others to include, in general, any incident, experience, or outcome that meets all of the following criteria:

• Unexpected (in terms of nature, severity, or frequency) given (a) the research procedures that are described in the protocol-related documents, such as the Institutional Review Board-approved research protocol and informed consent document; and (b) the characteristics of the subject population being studied.
• Related or possibly related to participation in the research (in the guidance document, possibly related means there is a reasonable possibility that the incident, experience, or outcome may have been caused by the procedures involved in the research); and suggests that the research places subjects or others at a greater risk of harm (including physical, psychological, economic, or social harm) than was previously known or recognized.

An incident, experience, or outcome that meets the three criteria above will warrant consideration of substantive changes in order to protect the safety, welfare, or rights of subjects or others. These events will be reported to the Principal Investigator within 48 hours with subsequent discussion and decision made regarding any action that will be taken.

All reportable serious events related to study participation will be reported to the Einstein Institutional Review Board at Phone: 718-430-2253

If there is a serious adverse event related to study participation, the PI is required to submit a completed Adverse Event Report to the Institutional Review Board.
